Thermoplastic paintable polyolefin composition

ABSTRACT

A paintable, scratch-resistant, thermoplastic composition containing 40-70% by weight of total polymer of an uncured copolymer of ethylene and higher α-olefin, said copolymer containing at least 67 weight percent ethylene units and having a Mooney viscosity of from 40-80; 30-60% by weight of total polymer of crystalline propylene polymer; and 20-50 parts carbon black per 100 parts of total weight of polymers having an oil absorption number of 50-140 cc&#39;s per 100 grams and a mean particle diameter of about 34-77 millimicrons.
